The latest version routes zap different and is no longer named as g0, it will be just 1 or 2 0r 3 as in channel

To use the zaptel routing you will need to change context in zapata.conf from " from-pstn " to " from-zaptel "
When that is done goto freepbx and select Zap Channel DID's
enter the zap channel that shows in detect hardware, so channel would be 1
Give it a description
And put in your zap DID
save and submit

Then goto inbound routes and add the description and the same DID and send to where you want
